Obesity is a civilization disease of the 21st century. The prevalence of obesity and overweight among children and adolescents is constantly increasing. BMI (body mass index) and WHR (waist to hip ratio) are methods of obesity assessment recommended by the WHO. Also, the WtHR (waist to height ratio), which takes into account height, is one of the most popular methods of diagnosing childhood obesity. A more recent diagnostic indicator is the FMI (fat mass index), which considers the percentage of the patient's body fat.
was to compare the methods of assessing obesity in children and adolescents using the following indicators: BMI, WHR, WtHR, and FMI and to determine the consistency of the results obtained with them.
The study included 195 children aged 11-18 years, from whom the following data were collected: height, weight, waist circumference, and percentage of body fat. The calculated indices (BMI, WHR, WtHR, FMI), expressed in SDS, were compared using the Bland-Altman test, Passing-Bablok regression, and the slope chart.
The fewest diagnoses of obesity were shown by FMI SDS (15.9%) and the highest by WHR SDS (28.7%). WHR SDS showed the least consistent results with BMI SDS. Significant statistical differences were found between BMI SDS and both FMI SDS and WtHR SDS.
BMI, as the most acceptable obesity indicator, can be used as a screening method for assessing obesity. However, patients with boundary BMI values should be examined more precisely, using more than one index. FMI is recommended.
肥胖是 21 世纪的文明病。儿童和青少年的肥胖和超重患病率不断上升。BMI（身体质量指数）和 WHR（腰臀比）是世卫组织推荐的肥胖评估方法。此外，考虑到身高的 WtHR（腰高比）是诊断儿童肥胖症最常用的方法之一。最近的诊断指标是 FMI（脂肪质量指数），它考虑了患者体内脂肪的百分比。
比较使用以下指标评估儿童和青少年肥胖的方法：BMI、WHR、WtHR 和 FMI，并确定用它们获得的结果的一致性。
该研究包括 195 名 11-18 岁的儿童，收集了以下数据：身高、体重、腰围和体脂百分比。计算出的指数（BMI、WHR、WtHR、FMI）以 SDS 表示，使用 Bland-Altman 检验、Passing-Bablok 回归和斜率图进行比较。
FMI SDS 显示肥胖诊断最少（15.9%），WHR SDS 显示肥胖诊断最多（28.7%）。WHR SDS 与 BMI SDS 的结果最不一致。BMI SDS 与 FMI SDS 和 WtHR SDS 均存在显著统计学差异。
BMI 作为最可接受的肥胖指标，可作为评估肥胖的筛选方法。然而，边界 BMI 值的患者应使用多个指标进行更精确的检查。建议使用 FMI。
